Answer this about Echocardiology Technique
A 70 year old with chronic lung disease and with a strong family history of ischaemic heart disease presents with atypical chest pain. An ECG is suggestive of ischemia. In view of the history of chronic lung disease a pharmacologic stress echocardiography is organised. What is the most likely pharmacologic agent
a) Dipyridamole
b) Adenosine
c) Dobutamine
d) atropine
e) Arbutamine
The correct answer is B
Explanation
Adenosine is by far the most commonly used pharmacologic agent in nuclear perfusion imaging. It can be used like dipyridamole and is typically infused at a maximum rate of 140 mg/kg per minute during imaging. The mechanism of action is probably identical to that of dipyridamole. However, adenosine has a much shorter half-life, and thus an antidote is usually not necessary in the event of an adverse reaction.
